Experimental Validation of Off-design Combustion for Liquid-propellant Rocket Engine High-frequency Instability

open access: diamondTransactions of the Japan Society for Aeronautical and Space Sciences, 2021
The mechanism causing high-frequency combustion instability was presumed to be the progression of combustion at an off-design location; that is, in the vicinity of the faceplate. Experiments were carried out to prove this.
